The first electronic computer was born in 1946.

The world's first general-purpose computer "ENIAC" was born on February 14, 1946 at the University of Pennsylvania. The inventors are Americans John W. Mauchly and J. Presper Eckert.

The U.S. Department of Defense uses it for ballistic calculations. It is a huge thing, using 18,000 electron tubes, covering an area of ​​170 square meters, weighing 30 tons, consuming about 150 kilowatts of power, and can perform 5,000 operations per second. This seems insignificant now, but at the time it was Unprecedented. ENIAC uses electron tubes as components, so it is also called a tube computer and is the first generation of computers. Because the electron tubes used in electron tube computers are large in size, consume a lot of power, and are prone to heat, they cannot work for too long.

Computer, commonly known as computer, is a modern electronic computing machine used for high-speed calculations. It can perform numerical calculations, logical calculations, and has storage memory. Function. It is a modern intelligent electronic device that can run according to the program and process massive data automatically and at high speed.

It is composed of a hardware system and a software system. A computer without any software installed is called a bare metal computer. It can be divided into five categories: supercomputer, industrial control computer, network computer, personal computer, and embedded computer. The more advanced computers include biological computers, photon computers, quantum computers, etc.

Computer inventor John von Neumann. The computer is one of the most advanced scientific and technological inventions in the 20th century. It has had an extremely important impact on human production activities and social activities, and is developing rapidly with strong vitality. Its application fields have expanded from its initial application in military scientific research to various fields of society. It has formed a huge computer industry, driven technological progress on a global scale, and triggered profound social changes. Computers have been used in general schools and enterprises. Public institutions have entered the homes of ordinary people and become an indispensable tool in the information society.

Computer applications are becoming more and more common in China. After the reform and opening up, the number of Chinese computer users continues to rise, and the application level continues to improve. In particular, applications in the Internet, communications, multimedia and other fields have achieved good results. From 1996 to 2009, the number of computer users increased from 6.3 million to 67.1 million, and the number of networked computers increased from 29,000 to 59.4 million. Internet users have reached 316 million, and wireless Internet users have 670 million mobile users, including 117 million mobile Internet users, ranking first in the world.
